Question

A) What is the value of x?

B) What is the value of y?

C) What is the best classification for the triangle?

Answer 1

Answer: x = 14; y = 74; Isosceles and Acute

Step-by-step explanation: 3(x+7) = 3x + 21

Isosceles triangles have congruent base angles making 63 = 3x +21

Solve for x.

All angles of a triangle add up to 180 making y = 180 - 63 - 63.

Isosceles because two sides are congruent. And acute because all angles are under 90.
